New light scattering portal

Any comments, suggestions or hints are welcome.

Especially I would like to encourage you to make your light scattering programs available to other scientists or students in the field. Why to reinvent the wheel!

Kind regards,

New software package for numerical light scattering simulations NAOPC and MTGRP

 Light scattering properties of clusters are important for the analysis of the observed data to infer the physical properties of the particles with possibly aggregate structures, such as cometary dust, biomass burning aerosols in the Earh's atmosphere, etc.

The NAOPC (Numerical Averaging of Optical Properties of Clusters) package extends the power of the T-matrix method for clusters of spheres, which is often used in the light scattering study of aggregates, in terms of

1) maximum number of monomers, which can be treated

2) computation efficiency by parallel computations. 

The MTGRP (Mersenne Twister Group of Particles) package is used to generate a medium of the spherical shape with spherical inclusions (in vacuum) (e.g., clusters of spheres or just two spheres in contact). The NAOPC and MTGRP packages can be used to study light scattering of media composed of spheres.
